What would be the process to give the clock the current time? Would it have to be resynchronized on every full shutdown? How would we handle the drift of time? ( I suggest occasional synchronizations between phone & chip) And most importantly: how much time would it take to implement a deep sleep / wake cycle synchronized with an internal clock.

sure we can have the clock synchronize with the phone, but we need to make a system where the time can never be less than last saved time to prevent a man in the middle attack.
